The tower of the extrahighvoltage (EHV) transmission line is heavy, tall, and it has longer cross arm and complex structure.
特高压线路的铁塔重量大、铁塔高、横担长、结构复杂。

The device has the function of intelligence identify and online surveillance and gets the great effect to keep away accident of extrahighvoltage power line.
In accordance with the high and extrahighvoltage long distance transmission line, this paper presents a fault location method based on two terminal information of self synchronous rectification.
